论文摘要
二极管是基本的电子组件之一。它具有与空间/时间逆转对称性损坏有关的非逆转电流响应。在这里，我们证明了在零磁场上运行的超导二极管的原型。它们基于常规的niobium Planar Josephson连接，其中空间/时间对称性通过从不均匀的偏见和被困的Abrikosov涡流中的自我场效应和流浪场的组合结合而打破。我们证明，此类二极管中临界电流的非交流能力可以达到数量级，而整流效率可以超过70 $ \％$。此外，我们可以通过更改偏置配置和捕获/删除涡流来轻松更改二极管极性并开/关。这有助于内存功能。我们认为，此类二极管 - 内存可用于未来的内存超导计算机。
Diode is one of basic electronic components. It has a nonreciprocal current response, associated with a broken space/time reversal symmetry. Here we demonstrate prototypes of superconducting diodes operational at zero magnetic field. They are based on conventional niobium planar Josephson junctions, in which space/time symmetry is broken by a combination of self-field effect from nonuniform bias and stray fields from a trapped Abrikosov vortex. We demonstrate that nonreciprocity of critical current in such diodes can reach an order of magnitude and rectification efficiency can exceed 70$\%$. Furthermore, we can easily change the diode polarity and switch nonreciprocity on/off by changing bias configuration and by trapping/removing a vortex. This facilitates memory functionality. We argue that such diode-with-memory can be used for a future generation of in-memory superconducting computers.
